Model 940 PositionServo Drives combine motor drives with simple motion controllers.
A Basic-like motion-programming language provides high-performance indexing and positioning, but the units can also accept traditional drive signals (analog and step/dir) from a motion controller. They come with a programmable memory chip that is removable. It lets servocontrol parameters and motioncontrol programs transfer from one drive to another in seconds, even without applied power.
